Abstract

A method for rapid direct cooling of a hot-rolled wire rod comprises the steps of : transporting a hot-rolled and coiled wire rod (1) on a conveyer (3) in a state that the wire rod is in a form of continuous series of loops ; and blasting air-water mist (18) to the wire rod and blasting air to the back side of the wire rod from below to cool the wire rod at a rate of 10 to 100 °C/sec. during the transportation, the air-water mist having an air to water ratio of 200 Nm³/m³ or less which is prepared from water of 0.5 to 10 m³/min. Furthermore, a method for rapid direct cooling of a hot-rolled wire rod comprises the steps of : transporting a hot-rolled and coiled wire rod (1) on a conveyer (3) in a state that said wire rod is in a form of continuous series of loops, having the wire rod advanced in zigzag during the transportation; and blasting air-water mist (18) to the wire rod and blasting air (5) to the back side of the wire rod from below to cool the wire rod at a rate of 10 to 100 °C/sec. during the transportation, the air­ -water mist having an air to water ratio of 200 Nm³/m³ or less which is prepared from water of 0.5 to 10 m³/min. The air-water mist can be alternated by spray-water.
